Sandvik Coromant 5732366 Indexable Boring Bar 0.63 in Rh

Product Description

The SANDVIK COROMANT 5732366 is a solid carbide indexable boring bar in the CoroTurn 107 series, designed for internal boring and turning operations on CNC lathes and turning centers. It features a 1/2-inch shank diameter, an 8-inch overall length, and a minimum bore diameter of 0.63 inches (16 mm). The toolholder uses screw clamping to secure a single TCMT 1.81.51 insert and delivers coolant through the bar body to the cutting zone. The neutral rake geometry and E-STFC toolholder style suit a wide range of internal diameter finishing and semi-finishing applications. This bar is installed by machinists and CNC tooling technicians in production and job-shop environments.

This boring bar is suited for both boring and turning operations where a compact, rigid tool is required to reach minimum bore diameters starting at 0.63 inches. The CoroTurn 107 series is commonly applied in residential and industrial component machining, including small-diameter internal features on steel, aluminum, and similar workpiece materials. The multi-use designation allows the same holder to support boring and turning applications, reducing tooling inventory. Its solid carbide construction provides stiffness at extended reach relative to the 0.5-inch shank diameter.

Key Features

• Solid carbide body for rigidity and minimal deflection in small-bore applications
• Coolant-through design directs cutting fluid directly to the insert and cutting zone
• Screw clamping insert retention for repeatable positioning of TCMT 1.81.51 inserts
• Neutral rake angle (0 degrees) suitable for a broad range of workpiece materials
• Multi-use capability supports both boring and turning from a single toolholder
• Right-hand cut orientation with E-STFC toolholder style

Compatibility

Compatible with TCMT 1.81.51 inserts. Insert inscribed circle is 0.25 inches (6.35 mm). This toolholder is part of the CoroTurn 107 series.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before setting or changing the insert or toolholder. Secure the shank in the turret or boring head to the manufacturer-specified clamping torque for the machine tool, using appropriate torque tooling. Verify minimum bore clearance against the 0.63-inch minimum bore diameter before beginning a cut.
